CVE-2025-25060: AssetView Authentication Bypass Vulnerability

CVE-2025-25060 Overview

CVE-2025-25060 is a missing authentication vulnerability affecting Hammock AssetView and AssetView CLOUD. The flaw allows a remote unauthenticated attacker to access critical functions over the network. Successful exploitation lets the attacker obtain or delete files on the server hosting the product. The issue is tracked under CWE-306: Missing Authentication for Critical Function. Public references include the JVN Security Advisory and the Hammock Security Information bulletin. The EPSS score is 0.703% at the 72nd percentile, indicating moderate near-term exploitation likelihood.

Critical Impact
Remote unauthenticated attackers can read and delete files on AssetView servers, exposing IT asset inventories and enabling destructive actions against management infrastructure.

Technical Details for CVE-2025-25060

Vulnerability Analysis

The vulnerability stems from a critical server-side function in AssetView and AssetView CLOUD that does not enforce authentication. An attacker reaches the function directly over the network without supplying credentials or any user interaction. Once accessed, the function exposes file operations against the host filesystem.

The practical consequence is twofold. First, an attacker can retrieve files from the server, which may include configuration data, asset inventory exports, log files, and other sensitive operational content. Second, the same exposure permits file deletion, which can disrupt the asset management service and destroy forensic evidence.

AssetView is widely deployed in Japanese enterprises as an IT asset and endpoint management platform. Compromise of this server places organization-wide endpoint inventory data, software license records, and management agent configurations at risk.

Root Cause

The root cause is the absence of an authentication check on a critical function, classified as [CWE-306]. A code path that performs privileged file operations is reachable by anonymous network clients. The function should require a valid authenticated session and authorization check before executing any filesystem action.

Attack Vector

The attack vector is network-based and requires no privileges or user interaction. An attacker who can reach the AssetView management interface, whether internet-exposed or accessible from a compromised internal host, can invoke the vulnerable endpoint directly. No code execution primitive is required; the attacker uses the intended but unauthenticated function to read or remove files.

The vulnerability mechanism is described in the JVN Security Advisory and the Hammock Security Information. No public proof-of-concept code is currently available.

Detection Methods for CVE-2025-25060

Indicators of Compromise

Unexpected HTTP requests to AssetView management endpoints from external or non-administrative source addresses
Missing or deleted files in AssetView server directories, including configuration, log, or asset database files
Outbound transfers of large archives or backup files from the AssetView server without a corresponding administrative task
Anonymous sessions in AssetView access logs invoking file-handling functions

Detection Strategies

Review AssetView web server and application logs for requests to file-handling endpoints lacking an authenticated session identifier
Correlate filesystem modification events on the AssetView host with originating HTTP requests to identify unauthenticated triggers
Baseline normal administrative activity and alert on file read or delete operations originating from the AssetView service account outside maintenance windows

Monitoring Recommendations

Enable verbose access logging on the AssetView management interface and forward logs to a central SIEM for retention and analysis
Monitor network flows to the AssetView server and alert on connections from sources outside the administrative subnet
Deploy file integrity monitoring on AssetView configuration directories, asset databases, and log paths to detect unauthorized deletion

How to Mitigate CVE-2025-25060

Immediate Actions Required

Apply the vendor-supplied fix referenced in the Hammock Security Information advisory as soon as it is available for your deployment
Restrict network access to the AssetView management interface so it is reachable only from trusted administrative subnets
Audit AssetView server filesystems and logs for evidence of unauthorized file access or deletion prior to patching
Rotate any credentials, API keys, or certificates stored on the AssetView server that may have been exposed

Patch Information

Hammock has published remediation guidance through the Hammock Security Information advisory dated March 25, 2025. Coordinated disclosure details are available in the JVN Security Advisory JVN#26321838. Customers should follow the vendor's upgrade procedure for both on-premises AssetView and AssetView CLOUD deployments.

Workarounds

Place the AssetView server behind a VPN or jump host so the management interface is not reachable from untrusted networks
Apply firewall rules to allow inbound traffic to AssetView only from explicitly listed administrator workstations
Disable or remove network exposure of any unauthenticated file-handling endpoints identified in the vendor advisory until patching is complete

bash

# Example: restrict AssetView management port to an administrative subnet
# Replace 10.0.10.0/24 with your administrator network and 443 with the AssetView port
iptables -A INPUT -p tcp --dport 443 -s 10.0.10.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
